The nature of Transformers collecting is such that the collections themselves inevitably take some kind of shape, and when we recognise where that shape is headed we might try and complete it. Every area of Transformers has its toughies, or ‘grails’ but as our contributors suggest this week, a grail need not always be a rare or expensive figure. These types of figures and targets change and shift over time as our interests do, and what I consider a grail today is quite different to my description of it a decade and a half ago. The whole concept of it changes as we capture some of these milestone Transformers or realise an achievement.
